[bazel] Build `rom_ext_signer` with Bazel

This commit:
- adds `BUILD` files for the rom_ext_signer and lib, and
- adds the `pkcs1v15` feature to mundane Bazel build to support the above.

This enables integrating the current signing tool into the
`opentitan_functest` Bazel macro. Note, in the future, the `rom_ext_signer`
functionality will be integrated into opentitantool.

This addresses a task in #10864.
